Description
Technical Field
The utility model belongs to the sewage treatment field.
Background
The MBBR technology is widely applied to sewage treatment and is characterized in that suspended fillers are added into a biochemical tank, so that the load of microorganisms is improved, and the tank capacity and the investment are reduced. But the suspended filler will move with the water flow. In order to maintain the distribution of the suspended fillers, a fixed intercepting screen is usually arranged to control the loss of the fillers, but the fillers are gradually accumulated on the surface of the fixed screen, and even if aeration purging is added, the fillers still block at the screen, so that unsmooth water flow and even blockage are caused. When the biological pond is subjected to reflux in a large proportion, the blockage is more serious, and the treatment function of the biological pond is reduced.
Disclosure of Invention
MBBR technology anti-clogging device which characterized in that: drive drum screen cloth pivoted driving motor 1 connects speed reducer 2, and metal fixed frame 3 is inside from outer to inner has set gradually rubber slab, brush, drum screen cloth 5, and drum screen cloth center is equipped with axis of rotation 6, is provided with drum screen cloth support 7 in the drum screen cloth 5, and the suspension is packed and is set up outside metal fixed frame.
Furthermore, the cylindrical screen adopts a mesh screen or a grid type, and the grid gap or the grid gap is less than 10 mm.
Furthermore, the metal fixing frame, the cylindrical screen and the support are made of stainless steel.
The pool shape adopts a circulating runway form, and the circulating flow in the pool keeps the flow speed less than or equal to 0.3 m/s. Especially, the flow velocity near the stirrer can reach 0.4-0.5 m/s. The water holes and the device are arranged near the stirrer, so that the aggregation of the filler can be effectively reduced, and the filler circularly flows in the tank.
And a water passing device is arranged in the water passing hole, so that the filler blocked on the surface of the screen mesh is automatically cleaned, and the normal operation of the MBBR system is maintained.

Description of numbering:
1 driving a motor; 2, a speed reducer; 3 a metal fixing frame; 4 rubber plate (outside) and brush (inside); 5, a cylindrical screen; 6, rotating the shaft; 7, a cylindrical screen support; 8 suspending the filler.
Detailed Description
The whole device has the specific structure that: the driving motor 1 is connected with the speed reducer 2, the rubber plate, the brush and the cylindrical screen 5 are arranged in the metal fixing frame 3 from the inside to the outside, the center of the cylindrical screen is provided with the rotating shaft 6, the cylindrical screen support 7 is arranged in the cylindrical screen 5, and the suspension filler 8 is arranged outside the metal fixing frame.
1) Mounting location
The device is arranged at a water passing hole from the anoxic tank to the aerobic tank.
Firstly, the pool shape design adopts a runway shape, which is convenient for the circulation flow of water flow;
secondly, in order to ensure better uniform distribution of the suspended filler and avoid filler aggregation, the water outlet is arranged near the stirrer. Locations with higher water flow velocities are selected, for example greater than 0.4 m/s.
2) Function and connection
Driving motor
The cylinder screen is driven to rotate, a time relay is adopted for control, and the cylinder screen rotates for 1 minute at an interval of 10 min.
The power is 0.18 kw.
A speed reducer:
the vertical gear reducer is matched with the motor.
③ Metal fixed frame
Used for fixing the motor and the cylindrical screen. The outer side is welded with the metal embedded part of the tank wall.
Rubber plate and brush
The rubber plate and the brush are in soft contact between the cylindrical screen and the frame, and the two sides of the rubber plate and the brush are respectively provided with one side, so that the filler and other suspended matters which are easy to block on the surface of the screen can be removed. Can be drawn out from the top and replaced; preferably 80 to 100mm in width.
Cylinder screen mesh
The suspension packing can be prevented from being clamped in gaps by adopting a mesh screen or a grid, and the gaps of the grid or the gaps of the grid are smaller than 10 mm. The diameter of the cylinder is less than 1m, so that the occupied space is small, and the processing and the installation are convenient. 304 stainless steel or higher standard material is used and is connected with the central shaft through a bracket.
Rotating shaft
The cylindrical screen is fixed and kept stable by the bracket.
Seventhly, a cylinder screen support
The screen mesh is fixed on the rotating shaft, and the shape stability of the cylindrical screen mesh is ensured.
(viii) suspended filler
The important component of the MBBR technology is plastic tubular particles with the diameter of 1-2 cm, and the plastic tubular particles are suspended in water and easily block water holes.
3) Principle of action
The filler 8 approaches the screen 5 with the water flow, affecting the water flow. When the motor 1 drives the rotary drum 5 to rotate, the rubber plate and the hairbrush peel off the filler 8, so that smooth water flow is guaranteed.
Material of
Firstly, the frame, the cylindrical screen and the bracket adopt 304 and above standard stainless steel, thereby avoiding corrosion;
secondly, if the rubber plate is worn, the rubber plate needs to be replaced regularly.
Design of parameters
Firstly, the diameter of the cylindrical screen is not more than 1m, and if the hole opening is larger, a plurality of cylindrical screens are added;
and the width of the brush and the rubber plate is preferably 80-100 mm.
And thirdly, the control is flexible by adopting a time relay, and a mode of rotating for 1 minute for ten minutes can be adopted.
